is a very open microblogging
platform, but there are some Twitter limits and restrictions that all users must adhere to. If you want to make sure your Twitter account stays off the Twitter blacklist, make sure you understand the Twitter limits and abide by the Twitter restrictions listed below.
Daily Update LimitsYou can publish up to 1,000 total updates to your Twitter account per day from all devices combined (Web, cell phone, etc.). When you surpass 1,000 updates in a 24-hour period, you won't be able to make any additional updates until the time period passes.
Daily Direct Message LimitsTwitter limits direct messages to 250 total per day on all devices (Web, cell phone, etc.). As an alternative to Twitter direct messages, you can always ask people to send messages to your personal email account.
Daily API Requests
You can only make up to 150 API (application programming interface) requests to Twitter per hour. An API request is counted each time you refresh your Twitter page. In other words, each time you perform a function on Twitter, an API request is counted. There is no way to keep track of your API requests, and most Twitter users are unlikely to reach the 100 API requests per hour limit (third-party Twitter application
developers and power business users are the audience most likely to be affected by the Twitter daily API request limit). However, TweetDeck
does allow you to keep track of your Twitter API requests if you want to do so.
Follower LimitsYou can follow up to 2,000 people on Twitter without any problems, but once you follow 2,001 or more people, you'll face following limits. Twitter following limits are based on the ratio of the number of people you follow to the number of people who follow you. Twitter following limits vary based on that ratio. There is no set ratio to guide you, so the best course of action once you follow 2,000 people is to make sure you're building the number of people who follow you as well.
